When your company planner isn't showing the names of any employees in the top filters section, this is down to a resolution error in your browser.
To resolve this:
Zoom all the way out on your browser using ctrl and - keys.
Then, zoom back in using ctrl and + keys until the names appear.
This should do the trick, but if not, log onto PeopleHR from an alternative browser or from incognito.
📌Note: Any value over 100% will be more likely to present resolution issues.
